Abstract: Heavy metals are introduced into fresh water by various industries and are easily digested by fish and other aquatic organisms. Low concentrations can be toxic because heavy metals can undergo bioconcentration. Toxic heavy metals of particular concern in industrial wastewater treatment include zinc, copper, nickel, mercury, cadmium, lead and chromium. The purpose of this study was to determine the potential of peanut shells to remove cadmium and copper from contaminated water. Batch method was used: parameters such as pH, contact time and initial metal concentration were studied.
